Ramifier stacking

Sorry I couldn't reply to the Ramifier thread

no. you definately can NOT stack two pressure boxes. That means Ramifier, EZ, Quad, VA, Bullydog, Banks, Volumizer are ALL incompatible with each other because they all a send pressure-fooling analog signal to the ECM.



you COULD stack certain pure pressure boxes (EZ, Ramifier, Quad, Bullydog) with the TST ONLY. just DONT do this with any of the fancier pressure boxes that use timing inputs (Banks, VA, Volumizer)



"pure pressur" boxes mean those that connect to the pressure port and the MAP sensor. Ramifier is a bit unique in that it is a "pure pressure" box from the connections standpoint but does some fancy boost fooling to get the power to come in early.



Here is my latest fueling box summary . I haven't updated it recently because I'm still waiting for Dennis to send me a Ramifier torque curve for the 555/305 engine.

D. Leno,



Could you provide directions on stacking the Ramifier and TST?

Tks.

Well, I've actually never hooked one up but Here'e something to try:



In order for the pressure box to work, it has to be connected to MAP. TST doen'st depend on MAP for fueling (it uses this for the boost guage and for boost fooling). Now on the other hand, the ramifier does depend on MAP -- things will probably go nuts if it isn't in control of this. So I'd try hooking up the ramifier directly to the engine MAP, then hook the TST up to the Ramifier MAP connector, then hook up the ECM to the TST MAP connector. daisy chain style. What will happen is that the ECM will see the TST boost fooler, which is just a capped passthrough from the Ramifier. Sincer the TST itself is looking at the Ramifier boost fooler, you should be in for some interesting gauge watching.



That isn't optimum but it should work. THe RAmifier will be lying to the TST, so what will happen here is that the Ramifier's fancy boost fooling will be plainly visible via the TST boost guage. In other words, watch the TST's boost guage to witness RAmifier boost fooling first hand. Does the TST boost gauge read higher boost levels than you expect at idle or other low boost conditions? If so, that is Ramifier boost fooling



Unfortunately, the TST will not give true boost readings for that configuration and it will clip whatever the ramifier gives it to the maxiumum boost reading allowed by TST. So this eliminates the TST boost guage as a reliable measurement of actual boost.



If your turned things around (TST to the engine MAP first), then the TST would send a capped passthrough boost signal to the Ramifier. Ramifier would never see full actual boost pressures -- it would always see the capped (fooled) signal from the TST. I don't think ramifier would like that.



oh, and when you do this, look out for smoke!
